LoongArch is a new RISC ISA developed by Loongson. It's a bit like MIPS or RISC-V. LoongArch includes both 32-bit and 64-bit versions (LoongArch32/LoongArch64). Loongson 3A5000 and 3A6000 are the two existing CPUs of LoongArch64 and is used for PC products. It's BIOS supports ACPI and UEFI-only boot. These CPUs supports SMP and SMT. At present only LoongArch64 is supported by linux kernel. Toolchain requirement: binutils >= 2.40 gcc >= 13.1 For details, please check the following links: https://lwn.net/Articles/861951/ https://loongson.github.io/LoongArch-Documentation/README-EN.html Signed-off-by: Weijie Gao --- include/target.mk | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'include/target.mk') diff --git a/include/target.mk b/include/target.mk index b5e3e7ff6f..68558601f3 100644 --- a/include/target.mk +++ b/include/target.mk @@ -264,6 +264,11 @@ ifeq ($(DUMP),1) CPU_TYPE ?= riscv64 CPU_CFLAGS_riscv64:=-mabi=lp64d -march=rv64imafdc endif + ifeq ($(ARCH),loongarch64) + CPU_TYPE ?= generic + CPU_CFLAGS := -O2 -pipe + CPU_CFLAGS_generic:=-march=loongarch64 + endif ifneq ($(CPU_TYPE),) ifndef CPU_CFLAGS_$(CPU_TYPE) $(warning CPU_TYPE "$(CPU_TYPE)" doesn't correspond to a known type) -- cgit v1.2.3
